Having problems with the file size of my animation

Ok ive started making some decent length animations with flash, but the filesize of them always seems to be a problem. I made the first, and it was around 2.8mb, not horrendesly big, but still a little oversized for what it was i think. Well ive just finished the 2nd, and its 5.5mb!!!

I dont know what the problem is, as ive compressed all the sound files and in the size report it says they are only taking up a few kbs each… Is the aniamtion taking up all this space??? Its just really annoying, because the animation isnt really that bad, but the ffile size is way too big. :frowning:

Can anyone recommend anything that will make the .swf smaller?
